The company, based at the Harfreys Industrial Estate, uses the road daily to transport normal to abnormal loads such as wind turbines, often bound for towns and cities across the country.

Mr Farrow, 70, who has run the business with his son Mark for its 22 years of existence, has been to two previous public inquiries about the matter, and for him the talk of the cost and the difficulties of the scheme is nothing new.

He said: “I can never see the point in trying to attract investment to the region while the A47 improvements have not been carried out.

“But at the same time I realise it’s an expensive piece of road to do it on, because there are about 70 or 80 lanes leading to fields, so you would have to have tracks each side so the farmers can access their fields on their tractors.

“There is a problem with that, it would cost more money if it was dualled. The rights of ways are so old you can’t get them rescinded.

“I am dubious about it happening in my lifetime.

“What annoys me is that every time we have a public inquiry both the political parties could not be in more agreement that it should be dualled. If everyone is in agreement then why hasn’t it happened?

“The cost is something that will be interesting because it is going to be surprising for a lot of people. They were talking about £30m around the year 1999, it must have doubled by now.

“It would be a benefit to see it dualled, lorries are heavy and we only run big trucks that are restricted to 40mph on that road.

“We would gain a speed advantage of 10mph which would benefit our business specifically but there would also be less accidents as it would mean you would not hit oncoming traffic so much.
